FIELD: metallurgy.SUBSTANCE: method is proposed for processing of lead and zinc concentrates, including annealing in oxygen atmosphere, supply of fluxes and a carbon-containing reducing agent with production of the charge and its subsequent recovery. The charge is recovered, which contains the annealed concentrate, the flux and the carbon-containing reducing agent at the mass ratio of the annealed lead and zinc concentrate and the reducing agent 1:(0.2-0.4) with air or oxygen blowdown, or blowdown with the air and oxygen mixture by means of upper non-submerging blowing.EFFECT: simplified process of lead and zinc concentrate processing due to separation of metals in one process.1 tbl, 1 ex |
